Intuitive "Object Oriented" User Interface Design - Designed for ease
of use, yet powerful enough to satisfy the most sophisticated experts. Common
data entry, browsing and control methods are used for non-trunked conventional
channels, trunking talkgroups, search configurations and Spectrum Sweeper
setups. The radio grows with you - you can start out
with a small, easy to manage configuration, then expand it whenever you
Powerful and Flexible Scan List Functionality – Allows you to arrange,
group and scan objects according to your preference, with no limit to the
number or types of objects in a Scan List, and no limit to the number of
Scan Lists an object can be a member of.
Menu Driven Programming with Context Sensitive Help - Each menu item
provides a few lines of help text that provide assistance with programming
and using the scanner.
Upgradeable CPU and DSP Firmware - You can easily keep your radio current
with software enhancements as they become available with free upgrades from
Flexible Free-Form Memory Organization - Memory is assigned as objects
are created using a sophisticated internal file management system. You are
not constrained to traditional bank/channel scanner memory layouts. No memory
is wasted as a result of bank/channel programming constraints. The scanner
has sufficient main memory capacity to store over 1,800
conventional channels, trunking talkgroups, search configurations and Spectrum
Sweeper objects in any combination, providing ample capacity for more sophisticated
hobbyists and professionals while keeping the database size manageable for
GRE's Exclusive V-Scanner Technology - Allows you to save complete radio
configurations within the radio, for recall into main memory as needed in
the field. This is similar to having a laptop computer and programming software
available anytime. You can use V-Scanners to store configurations for different
geographical areas or usage styles. Twenty-one V-Scanner Folders are provided,
each capable of storing over 1,800 objects. Total memory capacity of
main memory combined with V-Scanners is over 39,600 (1,800+37,800) objects!
Multi-System Trunking - Scans most common trunked radio system signaling
formats, including Motorola, EDACS Standard, EDACS Narrow, LTR and P25 trunked
radio networks. Talkgroup call and individual call monitoring are supported.
Supports trunking operation in virtually any land mobile radio band, including
700 MHz and the new Federal 380 MHz band!
P25 NAC Functionality - Much like CTCSS and DCS with analog signals,
P25 Network Access Code (NAC) is used to provide selective squelch operation
on conventional P25 digital channels. GRE's PSR-500 Advanced Digital Scanner
will detect the NAC that is being used on a P25 conventional digital channel,
and will allow you to program NAC codes to block transmissions that do not
have a matching NAC, including analog traffic on the same frequency!
Remote Control Capability - Can be used with third party application
software to remotely control the scanner from a personal computer.
Exclusive ALERT LED - Programmable tri-color LED can be configured to
illuminate or flash when certain objects are active. Eight user-defined
colors and brightness levels can be specified from thousands of possible
combinations. Provides visual alerts when certain objects are active, e.g.,
blue can be used to signal activity on a primary police call, red for fire,
Audible alarms - Programmable audible alarms can be configured to sound
when certain objects are active. Can be used in conjunction with, or separately
from, the ALERT LED described above.
GRE's Exclusive Automatic Adaptive Digital Tracking - When monitoring
Motorola and P25 digital systems, instantly adapts the digital decoder to
the digital modulation format of the transmitted signal, then analyzes the
digital signal 50 times each second and adapts to any subtle changes caused
by multipath or fading. No cumbersome manual adjustments are required.
GRE's Exclusive Digital AGC - Instantly compensates for low audio levels
that are very common on digital systems. The radio is easier to listen to,
and provides you with a more enjoyable scanning experience.
The Best Subaudible Squelch Decoder in the Scanning Industry - CTCSS
and DCS subaudible squelch coding is processed by the same powerful DSP
chip that is used for P25 digital decoding. Provides fast and reliable decoding
of subaudible squelch signaling with squelch tail elimination.
High Speed PC Interface - Uses GRE's 30-3290 USB cable in full duplex
mode at 6 times the speed of previous scanner models for PC transfer and
8 times the speed of previous models for radio-to-radio cloning.
Powerful Spectrum Sweeper - Quickly sweeps the scanner's frequency ranges
for transmissions from nearby transmitters.
Real-time Signal Strength Indicator - Shows relative strength of received
Trunking Control Data Output - Streams decoded trunking control data
from your PSR-500 to a personal computer for use with popular third party
trunking control channel monitoring software. No slicer needed! Also streams
NOAA weather radio SAME alert data!
High Contrast LCD Display - Provides one row of dedicated icons, and
four rows of 16 characters for programming and scanning operations.
and All Hazards Weather Alerting - GRE's PSR-500 Advanced Digital Scanner
can operate in dedicated SAME weather alerting mode, and alert you to severe
weather and other hazards in the specific area(s) that you select, or, the
scanner can check your local NOAA weather frequency periodically, even while
scanning, and alert you when an All Hazards alert occurs.
SKYWARN Storm Spotter Functionality – Provides instant, one button
access to frequencies used by storm spotter networks. You can monitor storm
conditions as they occur, and become aware of dangerous conditions before
the media or emergency management officials are able to announce them to
the general public.
Sleek, Compact Case Design - Has a Large Speaker for adequate volume
in most environments, and is designed for one-handed operation for ease
